Vyos first impression

So just started playing with Vyos, a community fork of Vyatta. Vyatta, now owned by Brocade, is a Linux, Debian based firewall / router distro running on X86 hardware. Renamed to Vyatta, a Brocade company, Brocade sell subscription models and appliances, built round the system. Vyatta has a webgui but the command line structure is I gather based on Juniper Networks Junos. A popular rivle to Cisco’s IOS.

Vyos is freely available and like it’s commercial cousin, runs on X86 hardware and a variety of virtulisation platforms. For my purposes I’ve just installed it to a VM under VMware Workstation. It is apparently possible to install to compact flash card for use in single board PCs, such as the PC Engines Alix. However the usual problem of limitting writes to that media apply, so logs need to be redirected.

At time of writing I’m using Vyos Helium, the second major release. V1.1.0. There is no webgui implemented yet, which personly suits me fine. Command line tools have a higher learning curve but are so much faster once you know them. The on board CLI help, like Cisco IOS is very useful. With the usual “?” offering options for the given mode. Yes like Privileged Exec and Global Configure, the familiar dropping into modes to perform sets of tasks applies here. The “configure” command gets you to global config. Changes are only applied once the “commit” command is given and “save” stores to disk.

One of my reasons for wanting to try Vyos, aside curiosity, is that I’ll be working on some Ubiquiti routers shortly. Their Edge OS is another fork of Vyatta and shares the same command syntax, at least thus far.

I’d say I like Vyos a lot at this point except for one major nag. That is, I’m not currently abel to get my Vyos VM working with VMware Virtual Network Adapters in Workstation. So I can’t connect this VM to the rest of my internal virtual networks. This maybe a misunderstanding on my part, some setting I’ve missed or possibly only works on VMware VSphere. The bare metal hypervisor. This is a great shame. I’ve posted to the Vyos forums but not had a reply. Anyway, will continue nosing around this issue.
